SINCE 1945
EXPERIENCE.
Custom designs and hundreds of standard units supporting
the aerospace, military, transportation, and communications
industries for signal routing and ATE applications.
Dow-Key Microwave, a leader in design and manufacture of switching products, acquired its matrix product line
from K&L Microwave (our sister company and part of Ceramic & Microwave Products group) in 1999. Over a
decade later, Dow-Key has expanded its line vigorously to meet the needs of today’s customers and has offered
over 150 custom designs and hundreds of standard units supporting the aerospace, naval, transportation, military,
and communication industries with signal switching applications.
Features and Capabilities:
The majority of our matrices consists of building blocks:
• 1U/3U/4U/6U chassis (other sizes are available)
• LCD/keypad or touch screen local control interface
• Ethernet/RS-232, GPIB/RS-232, EWEB (web browser), LNET (LXI) or SNMP remote control interfaces.
• Expandability by cascading specific units using CANbus and with master/slave control capability
• Dow-Key SCPI commands
• LabVIEW Graphical User Interface (GUI)
• Power combiners/dividers for fan-in/fan-out matrices
• Amplifiers and other passive components may be used on design basis.

Quality Assurance
Dow-Key Microwave Corporation is a renowned world class manufacturer with an unparalleled reputation for
product quality. Our commitment to continuous improvement initiatives within our products and processes, along
with the extensive series of internal and external assessments, ensures compliance in accordance with the AS9100
and ISO-9001:2000 standards requirement, which facilitates the registration process and continued certification
in order to secure Dow-Key’s future as a primary source for advanced RF switching products.
Facility
Dow-Key’s state-of-the-art facility presently consists of a single building totaling 36,000 square feet. To accomplish
design, manufacture, and test of Dow-Key products and assemblies, we invest heavily in capital equipment such
as vector network analyzers and synthesized sources, phase noise test sets, noise figure measuring equipment,
passive inter-modulation (PIM) test setups, thermal vacuum chambers, RF power meter, shock and vibration
station for environmental screening. In addition, we house two Class 7 clean rooms to support our high reliability
space and military projects.
Matrix models and solutions are classified with different types of switch configurations:
Switches: The matrix is populated with individual RF switches (DPT, SP6T, …, SP12T) and are not combined in
any other ways.
Blocking: Switches are combined in ways where some RF paths are blocked.
Crossbar (non-blocking): Any input can be connected to any output one at a time (1 input to 1 output).
Fan-Out (non-blocking): Each input fans out to all outputs such that any input can be connected to one or multiple
outputs simultaneously (1 input to many outputs).
Fan-In (non-blocking): All inputs are combined (fan-in) into each output, thus allowing one or multiple inputs to be
connected to any output simultaneously (many inputs to 1 output).

Matrix Solutions Using Electromechanical Switches
Dow-Key offers a wide range of electromechanical switching units, enclosed in 1U to 4U
(sometimes 6U or larger) chassis and with many available switch configurations. It meets
most application needs and if you cannot find what you are seeking, we can custom RF
systems per design specifications.
Benefits/Tradeoffs
• Available operating frequencies: DC-18 GHz, DC-26.5 GHz
and DC-40 GHz
• Electromechanical switches offer at least 1 million life cycles
• Perfect for both low and high power applications
• Longer switching time

PXI Switching Modules
PXI Switching Modules – Reconfigurable Modular Solutions
The PXI family offers three modules with different RF coaxial switch configurations: Dual SPDT,
DPDT, SP3T, SP4T, SP6T, 4x4 or 2x5. Depending on the model, the PXI solutions operate
either between DC -18 GHz or between DC - 26.5 GHz. Model 12K3S offers the user the
flexibility to combine up to three different switches in one single model and by removing external
RF cables on Model 14F32-1/4x4, the user can reconfigure the unit to terminated (e.g. SPDT
or SP3T) switches.
Additional Hardware
National Instrument PXI chassis (PXI-1036 or similar) is required.
14F3S-1/4x4
Software
Each switch can be controlled via Dow-Key LabVIEW, LabWindows, or Visual
Basic Graphical User Interface. Also, the modules are VISA and IVI compatible
and no additional drivers are needed.
